Description
RFID COMPOSITE FOR MOUNTING ON A METAL OBJECT BACKGROUND AND SUMMARY OF THE INVENTION The use radio frequency devices, known as RFIDs has been increasingly widespread since such devices, or their equivalents (such as EAS devices) provide numerous practical advantages in a number of environments. As a result RFID devices have been incorporated in a wide variety of products, including labels and tags, such as shown in granted US Patent Nos. US 6,281,795 filed February 8, 2000 (atty. dkt. 263-2198; 9945 US) and US 6,147,662 filed September 10, 1999 (atty. dkt. 263-2076; 9913 US), and U.S. patents 5,206,626, 5,497,140, and 5,448,110 (the disclosures of which are hereby incorporated by reference herein). However there is one environment in which it is difficult to use conventional RFID-containing devices, and that in association with metal objects.
For example if no special precautions are taken and an RFID-containing label or tag is affixed to a metal object, the metal is likely to de-tune the RFID antenna.
This typically is mitigated by the use of significant amounts of RF absorbing materials, or by spacing the antenna off of the metal. However if layers thick enough to properly space the RFID antenna off of the metal to which the label is affixed are utilized, then the labels are large and bulky. This reduces the efficiency of distribution and also makes printing on the device impractical using conventional printers used for printing documents.
According to the present invention a label, tag, or other composite device, is provided which alleviates the drawbacks discussed above. According to the present invention it is possible to provide a composite, such as a label or tag, that may be affixed to a metal object while substantially avoiding antenna de-tuning, butyet is not bulky or hard to handle, and can be readily imaged, including using conventional printers for imaging documents. This advantageous result is obtained according to the present invention by providing a foamable material o. layer of the composite label or tag) that expands in size and reduces in density when subjected to a foaming-initiating activation. For example the •e :30 foamable material layer may include an intumescent material, so that when heated it will decompose and/or form a gas and/or go through a phase change.
Therefore after eeoc.
printing the layer may be subjected to heat, microwaves, or other foaminginitiating activity and then applied to a metal object, or it may be heated or otherwise activated when it is applied (such as by a self-contained pressure sensitive, adhesive when in label form) to the metal object.
According to one aspect of the present invention there is provided a composite including: a first layer containing an RFID or EAS device; and a foamable material layer held in proximity with the first layer, the foamable material layer expanding in size and reducing in density when subjected to foaminginitiating activation, wherein the composite is configured to expand in width when said foamable material is subjected to foaming-initiating activation.
The foamable material layer may include an intumescent material, such as an azide compound which decomposes on heating, and/or a compound which will form a gas on heating, and/or conventional compounds that will phase change upon heating. Microwaves may also activate the foamable material, and other types of materials that foam in response to a condition may be utilized besides microwave-activated or intumescent materials.
The foamable material layer may also include RF radiation-absorbing materials, typically as fillers. A wide variety of such materials are commercially available including those shown in U S patents 5,202,688 and 5,691,667.
The composite may include a wide variety of other layers. For example there may be adhesive layers which operatively connect various other layers to each other. For example there may be a layer of adhesive operatively connecting the first and foamable material layers, either directly engaging both of those layers, or engaging one of the layers and an intermediate layer, or two 25 intermediate layers. The composite also preferably includes a printable surface layer, such as paper, on the opposite side of the first layer from the foamable material layer, and an adhesive, such as a pressure sensitive adhesive, of S conventional construction, can connect the RFID device to the paper layer either directly, or through one or more intermediate layers. Also the device, especially 30 with a printable surface layer, may be in label configuration and include a pressure sensitive adhesive layer operatively connected to the foamable material layer on the opposite side thereof from the first layer, either directly connected to 3 the foamable material layer or to one or more intermediate layers. The label may be linerless, or may include a conventional liner of silicone coated paper or like material.
Typically indicia is imaged on the printable surface layer, and only after that imaging in a conventional printer) is the composite subjected to the foaming-initiating activity. The pressure sensitive adhesive may adhere the composite to or adjacent a metal object, but because of the foamed layer (or multiple layers) and perhaps radiation absorbing material, especially as filler in the foamed layer, the RFID antenna will not de-tune during the operative life of the RFID.
According to another aspect of the present invention there is provided a method of utilizing an RFID, including the steps of: making a composite material having an RFID and at least one foamable material layer activatable by external stimuli; placing the composite in operative association with a metal object; and, applying external stimuli to effect foaming of the foamable material to space the RFID from the metal object.
In the method, step may be practiced so that the composite has a printable layer and the method then further includes the step imaging the printable layer (e g using a conventional document printer) prior to step In the method, step may be practiced before or after step In one embodiment the foamable material is an intumescent material, and step is practiced by applying heat, such as by using a hair dryer, soldering gun (that does not actually touch the composite), or a wide variety of other conventional devices. Also, step may be further practiced by adding RF radiation-absorbing material to the foamable material as filler.
BRIEF DESCRIPTION OF THE DRAWINGS FIGURE 1 is a side schematic view, with the size of the layers and the proportions exaggerated for clarity of illustration, of one form of an exemplary composite according to the invention; 0 •go• WO 02/25584 PCT/US01141122 4 FIGURE 2 is a side schematic cross-sectional view of the composite of FIGURE 1 with the liner removed and adhered to a metal object, and with the foamable layer foamed; FIGURE 3 is a top plan view of the composite of FIGURE 1; and FIGURE 4 is a box diagram showing an exemplary method according to the present invention.
DETAILED DESCRIPTION OF THE DRAWINGS FIGURE 1 schematically illustrates a composite 10 according to the invention. While certain layers are illustrated in FIGURE 1, that is for illustrative purposes only, and fewer or more layers may be provided including multiple foamable layers, as will be hereinafter described.
For the particular embodiment illustrated in FIGURE 1, starting from the top, there is a layer 11 having a printable surface 12, such as a paper layer of conventional construction as used in labels. The printable surface 12 may have indicia imaged thereon, as illustrated schematically at 13 in FIGURE 3, such as by using a conventional document printer.
The composite 10 also comprises an RFID (or EAS device) containing layer shown schematically at 14 in FIGURES 1 and 2, a portion of the RFID device shown schematically at 15. The layer 14 may comprise any conventional RFID layer, such as shown in the co-pending applications mentioned above, or in the patents mentioned above. The layers 11, 14 are operatively connected to each other, e.g. by a layer 16 of pressure sensitive adhesive (or under some circumstances other types of adhesive) directly adhered to both of the layers 11, 14, or adhered to one or both of them through one or more intermediate layers.
The composite 10 also comprises a foamable material layer 17. The layer 17 includes at least one material that is capable of foaming when exposed to external stimuli, such as a thermoplastic or thermosetting or a hybrid material intermixed with a foam forming agent that will form gas when activated. For example the foamable material of the layer 17 may comprise an intumescent material, such as an azide, or any other types of a wide variety of materials may be used for this purpose, such as compounds which will decompose on heating or WO 02/25584 PCT/US01/41122 exposure to other external stimuli, and/or which will form a gas, and/or which will undergo a phase change.
The foamable material layer 17 may also include other materials, e.g. as fillers, such as RF radiation-absorbing material, of a wide variety of conventional types, such as shown in U.S. patents 5,202,688 and 5,691,667. Other materials may also be present depending upon the particular foamable material or particular radiation-absorbing filler, or the like.
The foamable layer 17 may be operatively connected to the layer 14 by any conventional means, such as the adhesive pressure sensitive adhesive) layer 18 directly engaging both of the layers 14, 17, or directly engaging one and engaging an intermediate layer with the other, or engaging two or more intermediate layers.
When the composite 10 comprises a label, it also includes a layer 19 of pressure sensitive adhesive. The layer 19 may be directly adhered to the layer 17, or adhered thereto through an intermediary, or otherwise operatively connected to the layer 17. Where a linerless label is provided as the composite 10 then no liner of conventional construction is necessary, and there is a silicone or like coating on the surface 12. However in the embodiment illustrated in FIGURE 1 there is a conventional release liner 20, such as conventional silicone-coated paper.
FIGURE 2 shows the composite 10 of FIGURE 1 with the liner 20 removed from the adhesive layer 19, and with the layer 17 subjected to heat or other foaming-initiating stimuli. The adhesive 19 is adhered to the surface 21 of, or adjacent, a metal object 22, such as a pole, plate, housing, or the like. Because of the foaming action of the layer 17, RFID 14 is much more widely spaced from the metal object 22 than before the foaming (see FIGURE If RF radiationabsorbing material is provided as filler in the foamed layer 17, then the RFID 15 is even less likely to be de-tuned by the metal 22 during its operable life.
FIGURE 4 schematically illustrates an exemplary method according to the present invention. An RFID label or other composite, like the composite 10, is made using conventional techniques, as illustrated by box 25. Then the composite is imaged, e.g. using a conventional document printer because the composite is relatively thin, as illustrated at 26, with the indicia 13 (see FIGURE 3) being printed on the printable surface 12 of the composite 10. The composite 10 is WO 02/25584 PCT/US01/41122 6 applied to the metal object 22, as indicated schematically at 27 in FIGURE 4, and such as illustrated in FIGURE 2, and the procedure 27 may be practiced either before or after the composite 10 is exposed to heat (see box 28 in FIGURE 4) or other foaming-initiating stimuli.
It will thus be seen that according to the present invention a very effective and versatile composite, and method of utilization thereof, are provided which allow utilization of the composite directly on, in, or adjacent metal objects. While the invention has been herein shown and described in what is presently conceived to be the most practical and preferred embodiment thereof it will be apparent to those of ordinary skill in the art that many modifications may be made thereof within the scope of the invention, which scope is to be accorded the broadest interpretation of the appended claims so as to encompass all equivalent structures and methods.
